Storage for advanced smart video solutions

WD Purple™ Pro drives are designed for new generations of high-end AI-enabled
recorders, video analytics appliances, deep-learning servers and cloud solutions
that can benefit from high-capacity storage with high performance and additional
workload capability. WD Purple Pro drives feature AllFrame™ AI technology, which helps
reduce frame loss, improve overall video playback, and not only enables recording of
multiple streams per camera but also supports up to 32 AI streams per drive for deep
learning analytics within the system. WD Purple Pro drives also feature enterprise-class
performance, data integrity and drive reliability, especially in larger-scale systems and
enclosures where operational vibration is present.

drives are optimized to support up to 64 HD single-stream cameras12, and can also support the latest smart cameras that transmit multiple streams. With this flexibility, you can
upgrade or scale your security or smart video solution in the future.

Advanced workload capability for advanced systems

WD Purple™ Pro drives feature a workload rating up to 550TB/year⁶ to support the heavy
video data capture and analysis found in advanced AI-enabled recorders, video analytics
appliances, deep learning analytics servers and cloud-based storage. The combination
of streaming optimizations and enhanced durability and reliability make WD Purple Pro
smart video storage ideal for all analytics servers, whether processing video streamed
directly from cameras or large-scale captured video data sets.

Designed for reliable operation in advanced high-performance smart video solutions

With an MTBF of up to 2.5 million hours¹ (12TB, 14TB and 18TB³), WD Purple™ Pro drives
are engineered for advanced smart video solutions that operate 24/7. With tarnishresistant components and full multi-bay support, WD Purple Pro drives deliver reliable
operation in large scale surveillance systems even in harsh environments.

Field-proven high capacity

Now on its 6th generation, field-proven HelioSeal™ technology delivers trusted highcapacity WD Purple™ Pro hard drives (12TB, 14TB and 18TB³) for the massive storage
needs of AI-driven smart video and deep learning analytics.

Proactive storage management with WDDA

Western Digital® Device Analytics™ (WDDA) provides a wealth of storage device
parametric operational and diagnostic data compatible systems; algorithms interpret
the data and direct the system to alert system administrators of specific recommended
actions to address potential issues. WDDA is intended to empower OEMs, system
integrators, and IT professionals to better monitor and proactively manage supported
storage devices to maintain optimal operation.

¹ Projected values. When final, MTBF and AFR specifications will be based on a sample population and are estimated
by statistical measurements and acceleration algorithms under typical operating conditions, workload of 220TB/
year and drive temperature of 40°C. Derating of MTBF and AFR will occur above these parameters, up to 550TB
writes per year and 65°C drive temperature. MTBF and AFR ratings do not predict an individual drive’s reliability and
do not constitute a warranty.
² Not all products may be available in all regions of the world.
³ As used for storage capacity, one gigabyte (GB) = one billion bytes and one terabyte (TB) = one trillion bytes. Total
accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) =
1,048,576 bytes. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second,
and gigabit per second (Gb/s) = one billion bits per second. Effective maximum SATA 6 Gb/s transfer rate calculated
according to the Serial ATA specification published by the SATA-IO organization as of the date of this specification
sheet. Visit www.sata-io.org for details
⁴ This drive is in compliance with the European Union Directive 2011/65/EU and Directive (EU) 2015/863 on the
restriction of the use of certain hazardous substances in electrical and electronic equipment..
⁵ Controlled unload at ambient condition
⁶ Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is
annualized (TB transferred x (8760 / recorded power-on hours)). Workload Rate will vary depending on your
hardware and software components and configurations.
